IllusionCatalyst

From the IllusionCatalyst site:

IllusionCatalyst is a brand new set of instruments designed to increase artistic expression and productivity in Autodesk 3ds Max.

IC.Shape: Instruments for organic polygonal modeling. Draw and erase mesh edges like tracing lines with a pencil on paper, then deform and relax the surface like shaping clay by hands.

IC.Face: Instruments for facial rigging and animation. Bring characters to life letting them express every emotion and mood with a full range of controllers. No more gummy faces allowed.

IC.Mime: Instruments for keyframing and animation. Take a step and get the other one for free, control the flow of the action and each pose more easily. Forget about motion brakes.
